Answer:
5y+3x=-9
Step-by-step explanation:
Let us start by the general form of the standard equation, Ax+By=C. One way we can solve this problem is by finding the <u>slope-intercept form</u> of this equation, y=mx+b, and converting it into the standard equation. In the slope-intercept form, m represents the slope, b represents the y intercept.
From this problem, we are given both the slope and the y intercept. We know have the equation:
Great! Now let us rearrange the terms so that the y and x terms are on one side of the equation.
This seems right, but a standard equation must have coefficient values that are real numbers. So, A and B must be real numbers. We can do this by multiplying the entire equation by 5 and ridding the denominator of the A term.

Answer:
Step-by-step explanation:
O
3x² - 11x - 4 = 0
a = 3 ; b = -11 , c = -4
W
8x² + 12x = -1
8x² + 12x + 1 = 0
a = 8 ; b = 12 ; c = 1
L
x² + x = 6
x² + x - 6 = 0
a = 1 ; b= 1 ; c = -6
G
x²- 2x - 2 =0
a = 1 ; b = -2 ; c = -2
E
4x - 5 = -4x²
4x² + 4x - 5 = 0
a = 4 ; b = 4 ; c = -5
B
12x² +x -6 = 0
a = 12 ; b = 1 ; c = -6
R
2x² + 5x - 25 = 0
a = 2 ; b = 5 ; c = -25
A
6x² -5x - 4 = 0
a = 6 ; b = -5 ; c = -4
